CORE SERVICE
Custom Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic and audited for deployment.
- From Specification to Deployment: We handle the full lifecycle: requirement analysis, gas-optimized development, comprehensive testing, and final deployment.
- Protocol Integration: Seamlessly connect with existing DeFi primitives like
Uniswap V3,AAVE, orChainlinkoracles. - Security-First Development: Every contract undergoes manual review and automated analysis using tools like Slither and MythX, following
OpenZeppelinbest practices.
Deliver a battle-tested, auditable codebase in as little as 4-6 weeks, reducing your time-to-market and technical debt.

PROVEN PROCESS
Our Integration Methodology
A structured, four-phase approach to integrate a production-ready ERC-4337 bundler, minimizing disruption and maximizing security for your DAO's operations.
01
Discovery & Architecture Design
We analyze your DAO's governance flows, treasury management, and user onboarding needs to architect a custom bundler integration. This includes selecting optimal RPC providers, defining gas sponsorship policies, and planning for multi-chain expansion.
1-2 weeks

Frequently Asked Questions on ERC-4337 for DAOs
Get clear answers on integrating ERC-4337 account abstraction to streamline your DAO's treasury management and member onboarding.
A standard integration for a DAO takes 2-4 weeks from kickoff to mainnet deployment. This includes smart account factory setup, custom paymaster configuration, bundler node deployment, and comprehensive testing. Complex requirements like multi-chain support or custom signature schemes can extend this timeline, which we scope and quote upfront.
